This greenhouse experiment evaluated the influence of arsenic uptake by arsenic hyperaccumulator Pteris vittata L. and non-arsenic hyperaccumulator Nephrolepis exaltata L. on arsenic chemistry in bulk and rhizosphere soil. The plants were grown for 8 weeks in a rhizopot with a soil containing 105 mg kg(-1) arsenic. The soil arsenic was fractionated into five fractions with decreasing availabili...

Seventeen nuclear microsatellite loci (nSSR) were used to study the genetic diversity and historical demography of three Northeast Asian fir species: insular Sakhalin Abies sachalinensis (Fr. Schmidt) Mast., continental A. nephrolepis (Trautv.) Maxim. Kamchatka endemic gracilis Kom. Bayesian clustering, performed using STRUCTURE software separated considered species from each other divided popu...
